Ships may have Vented Lead Acid Batteries or Valve Regulated Lead Acid Batteries onboard; both battery types are common and require fairly low CAPEX investments. LEAD batteries are reliable and recyclable, functioning as backup power systems onboard vessels of all types.
The transportation of lead acid batteries by road, sea and air is heavily regulated in most countries. Lead acid is defined by United Nations numbers as either: The definition of ‘non-spillable’ is important. A battery that is sealed is not necessarily non-spillable.
If you do not ship this product type regularly, it would be wise to contact your chosen carrier in order to double check if they have any specific restrictions or packaging and labeling regulations. This diagram from UPS provides useful guidance on how to package wet lead acid batteries before shipping.
Non-spillable lead acid batteries (those that use Gel or Absorbent Glass Matt technology) require the same packaging as those filled with acid with the following differences: No acid proof liner is required. The box must be clearly marked “Non-spillable battery”.
Spillable lead acid batteries are regulated as dangerous goods under Class 8, controlled by UN 2794. These batteries are considered dangerous goods because of the possibility of fire if shorted. Furthermore, an acid spill can cause personal injury and property damage. Figure 2 shows the HAZMAT Class 8 label that is commonly seen on trucks.
Most Sealed Lead Acid batteries using Gel or Absorbent Glass Matt (AGM) technology is classed as non-spillable while even a ‘sealed’ standard lead acid battery with liquid electrolyte is spillable.
